Abstract (en)
An electrode for a vacuum circuit breaker being provided with a connecting portion (14) made of a material having the same resistivity as the arc running face portions (5B, 5C, 5D) across the corresponding arc guiding channel (13A, 13B, 13C) at the outer circumferential end (5E) thereof, wherein when assuming the outer diameter of the connecting portion as D1 and the inner diameter of the connecting portion as D2, the width (L) of the connecting portion is designed so as to satisfy the ratio D2/D1 to be in a range of more than 0.9 and less than 1.0. <IMAGE>
